SPECIFICATION forming part of Letters Patent No. 286,063, dated October2, 1883.

' Application filed August 6, W83. (X0 mode].)

To all whom it may concern-.-

Be it known that I, Onson N PERKINS, of Meriden, in the county of NewHaven and State of Connecticut, have invented a newlinprovement inShade-Holders; and I do hereby declare the following, when taken inconnec'tion with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure 1, a perspective View; Fig. 2, cctional plan view; Fig. 3, atransverse section through the ring, showing the introduction of theloop; Fig. 4, a modification.

This invention relates to an improvement in the construction of thearticle attached to gas and lamp burners to support a shade or globe,and commonly called a shade-holder, the object being to construct theholder so that the collar will make strong self-adjusting frictionalcontact with the lamp collar or burner to which it is attached; and itconsists in the construction, as hereinafter described, and moreparticularly recited in the claims.

A represents the collar or socket, which in internal diameter issomewhat larger than'the lamp collar, burner, or whatever it may be thatthe holder is to be attached to. I prefer three supporting'arms, l3 1)E, and these arms I make from wire, doubled at the extreme end and bentto receive the edge or flange of the shade in substantially the usualmanner for spring-arm holders, the legs spread as they approach thecollar, forming, respectively, two branches, 1) I), (Z d, c 0. Throughthe collar I make as many vertical slits fas there are arms, and througheach of these slits I introduce the two ends ofa narrow strip of sheetmetal, as seen in Fig. 3, the strip doubled to form a loop, g, upon theoutside of the collar. Then upon the inside I bend the two ends 7th ofthe loop backward and toward the surface, but so as to form a shank, 17,between the loop and the tnrnedalown portions, whereby the loop may havea certain amount of radial. play with relation to the ring. Then intoone of the loops, as 70, Fig. 2, I introduce and secure the ends of thetwo corresponding legs, I) e, of the arms B E. Into the second loop, Z,I secure the other leg 0 of the arm E, and one of the legs (I of the armD, and into the other loop, 921, I introduce the end of the other leg (Ioi the arm I), and also the other leg b of the The legs of each arm, are

but readily yielding, so that the loops, with .60

their respective legs, may be forced outward. The diameter orcircumference within the turned-downportions of the loops is somewhatless than the diameter of the collar or the burner to which the holderis to be attached,

and so that in applying the holder to such collar or burner the loopsare forced outward, and then when set upon the collar or burner thereaction of the legs forces the loops inward,

bringing their turned-down portions into strong frictional contact withthe collar or burner, whereby the holder will be firmly secured to thelamp or burner. I

I prefer to construct all the loops with radial play, as I havedescribed, so that all the legs will act as springs; but one only ofthe' loops may be thus free for radial movement, the others beingsecured to the collar, that one affording su'tlieient support for theholder;

but in. such case there will be less extent of So adjustment than whenthe three loops are made free for radial movement. The two parts or legsof the arms are bound together between their extreme ends and thecollar, as

at a, whereby their strength or elasticity is increased. One arm onlymay be thus divided, the other two arms being rigid, the one d1v1- sionof the said divided arm attached to the loop, so as to impart to theloop the same inward radial pressure, as seen in Fig. 4. I

also prefer the loop-like connection between the arms and socket; butthis connection may be otherwise made. I tl'lerefore do not WlSll tolimitmysel'l" to the combination of three arms thus constructed, or tothe necessary union of 5 either two arms in the same loop, it only beingessential to my invention that the holder shall have one of its armsdivided, the two parts diverging toward the collar, and so as to formconnection at two distant points, one of movement with the collar, andprovided upon its inside with a frictional surface.

I claim 1. The herein described shade-holder, cons sting of the centralcollar, radial arms to receive the shade, two or more of said armsdivided, the two divisions of the arms diverging toward the collar, thetwo divisions attached to the collar at points distant from each other,the one division of 01162111111 united by a loop to the correspondingdivision of the other arm, the said loop arranged through the collar forradial movement, and provided on the inside of the ring with africtional bearing-surface, substantially as described.

the connections with the collar having radial l 2. In a shade-holder,the combination of a collar with two or more supporting-arms, one ofsaid arms divided, the two part-s'diverging toward the collar and thetwo parts connected to the collar, one of said connections arranged inthe collar vfor radial movement, and pro: vided upon the inside of thecollar with a frictional bearing-surface under the spring-pressure ofthe divided arm, substantially as described.
